deva.bm® 302
deva.bm® is a metallic composite material consisting of a steel strip as a supporting backing and a sintered-on, self-lubricating bronze sliding layer. The solid lubricant (graphite or PTFE) dispersed in the sliding layer under preload enables the sliding bearing to be used without the need for maintenance.
The maintenance-free and self-lubricating material is available in different alloy variants and material thicknesses. The two-layer material structure enables the implementation of compact and highly resilient sliding bearing concepts that function reliably.
The percentage content of solid lubricant as well as its particle form and distribution vary depending on the alloy.
The advantages of deva.bm®
For different requirements, we choose between four different microstructures and additionally offer further features, e.g., type of steel backing, sliding layer with and without oil impregnation, surface structure, and additional solid lubricant deposits.
Generally for dry operation and water-lubricated applications
Standard material for general mechanical engineering
High static load
Low number of cycles
In the group of deva.bm® materials with a low graphite content, deva.bm® 302 is the typical standard material. It is characterized by a smooth sliding layer with running-in treatment (black) and stainless steel backing (1.4301).
Description
The sliding surface is not coated with running-in film
Technical characteristics
Without running-in film, the coefficient of friction in the running-in phase is similar to or slightly higher than in the steady-state operating phase
Applications
Description
The residual pores of the sintered material are additionally impregnated with oil
Technical characteristics
Applications
Description
Alternative supporting backings for different environmental conditions
Technical characteristics
Applications
Depending on the ambient medium and its influence on material corrosion.
Description
The sliding layer has a groove system. Groove depth: Max. down to the supporting backing
